If you've never used it before, Safari for Windows basically will give you a 'decent' idea of how your website or blog will look on a Mac. It's lightweight and feature rich.

Finding release notes on the Apple website (at least for me at this hour :) on this latest maintenance version of Safari was difficult .... but an educated guess based on usage since last night is (1) security improvements and (2) speed improvements and/or (3) Vista compatibility issues.

For those who wish to have the latest and greatest on their box, that's the scoop from Apple.

PS: It's FAST!

Update: This is what happens when I look at TechMeMe after a post :) The release notes are here.
